About the quark currents in leptonic decaies of pseudoscalar mesons
arXiv:hep-ph/0603147
Abstract
With usage of obvious mechanisms of quark currents the amplitudes of leptonic decaies of pseudoscalar mesons are investigated. The estimation for a constant of leptonic decay of the D+ meson is obtained, f_D+ ~ 0.23 GeV.
